This change adds robust wait mechanisms to prevent race conditions when
performing delete and save operations in the ERP system.
Changes:
- Add row number change detection after delete to confirm completion
- Add save button disappearance detection to confirm save completion
- Add row number range check (7000-8000) to skip specific rows
- Enable previously commented save button click
- Improve logging with detailed status messages
- Add timeout handling (10s for delete, 60s for save)
